Purpose

We surveyed ordering physician attitudes, knowledge, and behavior with regard to computed tomography (CT)-related radiation exposure at a large medical center.

Methods

Sixteen questions were sent via electronic survey to 350 physicians.

Results and conclusion

The ability to quickly rule in or rule out conditions effectively strongly influenced the decision to order CT (85 % -99 % ). Fear of litigation influenced CT ordering for those with less experience [odds ratio (OR)=2.3, P<.05]. Residents and primary care physicians were less likely to discuss risks/benefits of CT with patients (P¡Ü.03) compared to those with >5 years of experience (OR=4.0, P=.04).
